python2.7+Selenium3+firefox49

之前用的Selenium2，總是要找低版本的火狐才能使用

最近更新到了Selenium3後，和最新的firefox49就能比對使用，不過也碰到了一些問題

1. 要先将geckodriver.exe放到firefox的安裝目錄下，我這裡的路徑為C:\Program Files (x86)\Mozilla Firefox

2. python腳本：

from selenium import webdriver

driver=webdriver.Firefox(executable_path = 'C:\\Program Files (x86)\\Mozilla Firefox\\geckodriver.exe')

driver.get("https://www.baidu.com")

3.如果運作上述腳本報錯：Expected browser binary location, but unable to find binary in default location, no 'moz:firefoxOptions.binary' capability provided, and no binary flag set on the command line

請嘗試：

from selenium.webdriver.firefox.firefox_binary import FirefoxBinary

binary = FirefoxBinary(r'C:\Program Files (x86)\Mozilla Firefox\firefox.exe')

driver=webdriver.Firefox(executable_path='C:\\ProgramFiles(x86)\\MozillaFirefox\\geckodriver.exe',firefox_binary=binary)
